Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12730, here are decompositions:
- 17 + 12713 = 12730
- 41 + 12689 = 12730
- 59 + 12671 = 12730
- 71 + 12659 = 12730
- 83 + 12647 = 12730
- 89 + 12641 = 12730
- 191 + 12539 = 12730
- 227 + 12503 = 12730
Showing the first eight; more decompositions exist.
